2Y0 all tchom it may concern:

Be-it known that I, SIVERT MOE, a citizen oi the "United States, and aresidentof the city of Chicago; county of Cook, and State of Illinois,have invented certain new and useful Improvements in Mangles; and I do'hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon, which form apart of this specification;

This invention relates to improvements in mangles and more articularlyto a power operated mangle. n mangles of this class a large central drumor cylinder is heated by means of steam or in any suitable manner and aplurality of cloth covered pressure rolls are arranged longitudinallythereof and bearing upon its periphery and the fabrics to be mangled arepassed between said drum and therolls. In stopping all such mangles itis necessary that the pressure rolls be quickly raised-from the heateddrum to prevent'the fabric burning, and where individual adjustment ofeach end of each of the pressure rolls is necessary considerable time isconsumed which in many instances causes damage before the adjustmentcan-be made. Furthermore when it is desired to start the mangle it isobviously necessary to return the ressure rolls into engagement with theeated drum and when each pressure roll is thus individually adjusted itis diflicult to get uniform adjustment at each end of the rolls and withsuch machines the fabric is frequently-drawn oblique on the heated rolltearing or injuring the same.

The object of this invention is to provide in combination with a manglesuch as described, mechanism for instantaneously ele vating each of thepressure rolls out of contact with the surface of the heated roll ordrum and, furthermore to accomplish this adjustment either manually orby thepower used to drive the machine. Further-n" ore to ermitthepressure rollers to be returned mto positive engagement with thedrumsimultaneously. v

It is also an objectof the inventionto provide in conjunction with a.mangle and ad-' justing means such as described, means for utilizingpractically the entire periphery of theheated roller drum at alltimesand to thoroughly il "the fabric after mangling.

It-is aiur-t; eriobjeet of the inventionito --g provide a positivelyoperated perfectly ad-.

end of the pressure rolls.

justable device of the classdescribed in which the tension or ressure ofthe pressure rolls. upon theheate drum is at all times uniform at'bothendsof each pressure roll, and for the entire length of each pressureroll.

The invention consistsin the matters hereinafter described and morefully pointed out and defined in the appended claims.

In-the drawings: Figure 1 is a view in elevation taken at one end of amangle embodying my "invention. Fig. 2 is a fragmentary elevation of theopposite end of the machine. Fig. 3 is a view similar to Fig. 1 with theend frame member and adjusting mechanism removed. Fig. 4 is av viewartly in side elevation and partly in vertica section of a deviceembodying my invention. Fig. 5 is an en-. larged detail of one of thebearings for the Fig. 6 is an en'- larged sectional detail of one of thelower pulleys forthe conveying belt.v Fig. 7 is an enlarged fragmentarydetail of one of the adjusting shafts. Fig. 8 is a top plan View of thelower end of the same. Fig. 9 is an enlarged sectional detail of one ofthe adjusting rods and the bearing therefor. Fig. 10,is a detail of theadjusting mechanism.

In said drawings: A indicates a hollow drum-0r cylinder of largediameter and of the desired length which is j ournaled at its ends a'ato rotate in frame members B and B, each of which comprises aframe ofthe desired width and of a height to support the drum sufficiently abovethe foundation. Above the bearing for said drum said frame members areeachrovided with an integral semicircular arch which extends to the topof the drum and areco'nstructed to afiord great strength. One of thehubs or gudgeons a, of said drum of the cylinder is tubularcommunicating in-the drum, and opening thereinto is an exhaust pipeafi,on the outer end of which is secured a casting or fitting a having anexcompartment therein from which an inlet pipe a, extends through saidexhaust pipe, andinwardly to near the periphery of the drum. Saidcompartments are provided as shown, with an exhaust pipe and an inletpipe respectivel at all times in open communication wit thecorresponding pipes opening intothe drum. A stu'fling vbox or land isprovided-around the exhaust pipe in said hub to afford a tight joint,

Mounted' to slide radially in the upper arched portions 1), of ,theendframe members are supports D, one for each end of each of the pressurerollersD, of which in the present construction six are shown. Bear-' mgsor guides d are provided on each of said frame members as shown in Fig.1, having inwardly directed grooves thereinin which rest said bearingmembers or supports D Each of said bearing members D is provided at itsupper end with a flat head (1, and with a longitudinal slot, as shown inFigs. 1 and 5,-

Each ofsaid pressure rolls, as shown, is provided at the extremity of itsshaft, as shown in l igs. 2 and4, with a gear D of eater diameter thanthe roll, and

C thereby rivi said rolls therefrom and at a different perip eral speedfrom the drum Means are provided for shifting both segments Esimultaneously to adji st the re ls, comprising a shaft F, journaledlongitudinally of the frame on the front and near the bottom thereof.This is provided with a slots an hold 7 teeth which mesh with the gear.

gear. f thereon ada ted to be actuated by a worm f having a h rotate thesame. 1

- On the inner side of each frame member and secured on said shaft is adis; f on' which is secured a wrist pin f as shown in dotted linesinligs. 1 and 3, and engaged thereon and at the adjacent end of saisegments E is a connecting'rod I which when said shaft is rotated by theworm in one direction shifts the segments to elevate the rolls D andwhen rotated in theother brings the rollsinto positive engagement withthe hot drum.

' Means are provided for shifting the seg ments by power-for thispurpose, as shown, the inner end of the worm shaft is journaled in acasing f which affordsa hearing there for and is bolted to the frame asshown in higs. 1 and 4. A beveled ear f is secured on the end of saidshaft wit 'n the casin as shown in dotted lines in 1 'i'g. 4 and rotataly and wheel f 2 thereon to v secured on a transverseshaft f arebeveledgears f and f 7 intermeshing with op osite sides of the bevelgear f 4 through a slot in the casing'as shown in 1 ig. 4. Said shaft fas shown is journaled at the end of the casi by means of removablebearing blocks whic are boltedto said casing in a well known manner. Theinner side of each of said beveled gears fb is shaped to afford onemember of a clutch, and feathered on the shaft f, is a double clutchmember f adapt-' ed to eng'a e either of said beveled gears to' rotatethe s aft. A hand lever f, having an arm j, thereon which at its endengages said clutch member f 8 is pivoted on. a boss f on the casing forthegear and the inner end of said lever j is shdab y engagedon a 'rodfF, the upper end of which ispivotally engaged on the end of the segmentE adja* cent the connectin 'rod F and the lower. .end extends below t elever f an adjl; stable stop f is secured .on said rod above said leverand a sto f is pivoted'at the lower end of said ro and hinged to bear atits upper end against said rod below said lever f, permitting a limitedtravel of the rod before engaging the lever j". Said shaft f, ispositively driven by a sprocket chain f,

trained around 'a sprocket wheel on said.

shaft'and one on the driving shaft C.

Means are provided for utilizing practically the entire periphery of thedrum continuously in manglin for this urpose, as shown, a feed tableisprovi ed on one side of the machine below the first roll and on theopposite side and" at each end of the ment with a-si1itable wrench. Saidscrew same haspassed through the, machine and a length of said drum andthe upper/ lap of -margin thereof engage sprocket wheels '5 on each endof said shaft, as shown also the lower lap of said belt passes beneaththe one end of each of which engages a wrist! pin on said disk f, whichacts when the sha .F is rotated to elevate the pressure rolls to swingsaid pulley -H downwardly and inwardly. Beneath the feed table G isjournaled a pulley of a length corresponding with the heating drum andindicated by h, and provided at its outer end with a gear h, whichmeshes with a gear W, on a shaft if, the latter in turn meshing with agear h, on the driving shaft 0. Trained about said pulleys is a belt 72.equal in width to the which bears positively against the under side ofthe drum and the lower lap of which asses beneath a pulley h, as shownin ig. 3. A sprocket wheel h is secured-at each end of said pulley h andon which engages a sprocket chain it, one of which is ermanently securedalong each edge of the elt 72. A corresponding belt I also providedalong each edge with sprocket chains '11, such as before described, istrained over yulley I, adjustably supported on a bracket on one side ofthe frame and over a pulley I; secured on the shaft'h before described,the upperdapifof said belt passes beneath the pulley h", and the lowerlap .of the belt h, before described, as shown in Figs. 3. and 6, andthe sprocket chains '1', on each idlers il -4, journaled at the bottomof the frame. All of said pulley shafts are provided at their ends withsprocket wheels to engage the s rocket chains secured at the edges ofsaid be ts similar to the arrangement shown in Fig. 6, and whereby thebelts are positively driven and caused to run true about said pulleyswithout lateral slip, furthermore "0th belts are provided withtighteners, where the'tension on the belt may be varied as desired. Forthis urpose the connecting rod H at the point where the same engages thedepending arm of the bell crank H, is provided with a spring L, whichbears against the inner side of said arm and jam nuts Z, whereby thetension on the lower end ,of said bell crank may be ad'usted, therebyswin ing the other end of t e bell crank upwardly'to tighten the belt.The tightcner for the lower belt comprises at each side of the machine ascrew shaftL' provided with an angular head for engageshaft en ages in asuitable block which affords a b I and rotation of said shaft acts, tomove the pulley inwardly or outwardly to loosen orf tighten the belt.

As shown, a table Mis ositioned beneath the pulley I to. receive t efabric after the caring for the shaft of the pulley ledge or blademflext ends upwardly from the edge of each table 'and'bears lightlyagainst the belt' I, as shown in Fig. l, a strip the'fabric therefrom.

The operation is as follows: The pressure .rolls are each covered withfabric as usual, which for convenience is not shown, and are heated fromcontact with the hot drum.

When it is desired to operate the machine the lever j, is pressed downelevating its inner end and simultaneously throwing the clutch to engagethe ear f. The se ments-now start downwardly drawing the rdlls upon thedrum and the belt 71. is simultaneously tightened by the outward swingof thebell cranks.

When the segments reach the proper limit of travel the stop f engagesthe end of the lever j" shifting it to neutral position. If necessarythe belt I may be tightened by re.- tation of the screw shafts L. Havingadjusted the machine for operation (which can be ac complished almostinstantaneously) the fabric is fed over the table G to the firstpressure roll and is frmly pressed thereby and by succeeding rolls uponthe heated drum and carried around the same and delivered between thesame and the upper lap of the belth and thence is carried between thelower lap ofthe upper belt and the upper lap of the lower-belt, thesbeing heated by mutual contact and contact with the heated drumcontinues the operation. The pressure rolls having a s ghtly differentperipheral speed than the heated drum, the fabnc is smoothed thereby andthis action is continued in the travel of the fabric along the belts andat the delivery upon the table M the fabric is both smooth and dry.

, Should at an moment it be desired to top the operation 0 the mangle itcan be instantly accomplished by lifting the lever f to throw the clutchj into engagement with. the bevel gear f thus, driving the worm andshifting the'segmcnts to elevate the rolls, and at the same timeloosening the belt 72. per:- mitting the same to sag away from the lowerside of the heated drum, thus. avoiding the burning of the fabric,either of the rolls or the belt, or any fabric in the mangles which mayat that time be supported upon the upper belt. As the segments areelevated thetop shown in dotted lines in Fig. 7, permittin the rolls tolift high enough to recoverfabric.

The belt can obviously never raw ater? I ally on e p l y ec use of-thprocket chains, at the mar thereof aging over the sprocket whee for -p,,eye. and of course any suitable means ma- -be enfipleyeid to, tiihten orloosen theloqwer elt as esiled.

i0 ,usly a machinesuehas desembedpes sesses great stren th and theadvanta e of instant adjustability to enable an artic e to be instantlyreleased from the mangle at any point-in its passage therethrough. Ofcourse, the pressure rolls exert equal pressure throughout the length ofthe rolls. sequence uniformity of action is insured and, there being novariation in the stress applied to the fabric passing therethrough,tearing or injury of the fabric is practically an impossibility. 7

Obviously many details of construction may be varied. I therefore do noturpose limiting this application for patent 0t erwise than necessitatedby the prior art.
